Fair enough.  But, unless Kodo is replacing the JPQL parsing, I don't see
how you can get around this problem.  I suppose it's possible that other
performance improvements could negate the performance hit associated with
the reflective class loading.  But, it would seem that if Kodo 4.1 is using
OpenJPA, then these same type of issues would exist there.

Maybe this is the key part of your message -- no real performance testing
has been performed yet.  So, maybe we're just now experiencing and
discovering these performance concerns at the same time.
